2. Installation – understanding the basics
2.1.
Pellets
Wood pellets are manufactured by hot-extruding compressed sawdust which
is produced during the working of natural dried wood. The compactness of the
material comes from the lignin which is contained in the wood itself, and
allows the production of pellets without the use of glues or binders.
The market offers different types of pellet with characteristics which
vary depending on what mixture of woods is used. The diameter varies
between 6 mm and 8 mm, with a standard length in the range ¼” to 1
½”. Good quality pellets have less than 0.5% ash with a moisture
content which varies from 5% to 8% by weight.
Besides being an ecological fuel (exploiting timber residues to the
maximum and achieving cleaner combustion than is possible with fossil
fuels), pellets also have technical advantages. While good-quality timber
has a calorific power of 4.4 kW/kg (with 15% moisture, therefore after
about 18 months' seasoning), the equivalent figure for pellets is 5.3
kW/kg.
Fuel pellets
To ensure good combustion, the pellets must be stored in an area that
is free of humidity and protected from dirt. The pellets are usually
supplied in 40 lb. sacks, so storing them is very convenient.
Good quality pellets ensure good combustion, thus lowering the
emission of harmful agents into the atmosphere.
The poorer the quality of the fuel, the more
frequently cleaning will be necessary. Especially the
internal parts, such as the grate and the combustion
chamber.
The main certifications of quality for pellets in the European market are
DINplus and Ö-Norm M7135; these ensure respect of:

Calorific power: 4.9 kW/kg

Water content: max 10% of weight

Percentage of ashes: max 0,5% of weight

Diameter: 5 – 6mm

Length: max 30mm

Contents: 100% untreated wood, with no added bonding
substances (bark percentage 5% max)

Packaging: in sacks made from ecologically compatible or
biologically decomposing material
MCZ strongly recommends using certified premimun
quality pellet fuel in its stoves
The use of poor quality high ash fuel compromises
the running of your stove and could void the
warranty.
MCZ pellet stoves run exclusively on pellets with a
diameter of 6-8 mm with lengths from ¼” to 1 ½”.

INSTALLATION
IMPORTANT!
Installation and assembly of the stove must be
carried out by qualified personnel.
The stove must be installed in an area with adequate space to allow the
stove to be cleaned and maintained.
The stove must be positioned in such a way that the plug is accessible.
The site must be:
Provided with enough make up air for proper operation of the
stove.
4
15.5 In²
Have a properly grounded 110V outlet within 6‟
Installation and repair of the Ego/Star Pellet Stove should be done by a
qualified service person. The appliance should be inspected by a
qualified service person before use and at least annually. Every 2000
hours of effective work a temporary service warning appears in display
at each ignition, to remind the requirement of a periodical inspection. It
is imperative that control compartments, burners, and circulating air
passageways of the Ego/Star be kept clean.
2.3.
Example of pellet stove installation
OPERATING AREA
For proper operation and a good heat distribution, the stove must have
adequate make up air. This can be supplied by connecting the outside
air supply or by assuring that there is adequate ventilation in the home.
3”
In bedroom or bathroom installations the outside air
connection is required!
Locating the stove in a room with an explosive
atmosphere is prohibited.
40”
3”
If the walls are not flammable, position the stove with a clearance to
the rear of at least 2,5”.
For flammable walls, keep a minimum distance of 5” at the rear, 4” on
the sides and 40” at the front.
If the room contains objects which are believed to be particularly
delicate, such as drapes, sofas and other furniture, their distance from
the stove should be considerably increased. See page 16 for details.
Example of pellet stove installation
If the flooring is made of wood, provide a floor
protection surface in compliance with current
national standards.
2.4.
CONNECTION TO THE EXTERNAL AIR INTAKE
It is essential that at least as much air must be able to flow into the
room where the stove is installed as is required for proper combustion
in the appliance and for the ventilation of the room. This can be
accomplished by connecting the outside air feature on the stove or by
providing a ventilated wall pass through 15 sq in min.
The air intake must:

PELLET STOVES
Chapter 2
INSTALLATION AND USE MANUAL
page
11
Directly provide air to the room where the stove is installed
Must be protected by a grill, metal mesh or suitable guard, as
long as this does not restrict air flow.
be positioned where it will not be obstructed
MCZ strongly reccommends to install the air filter
provided with the stove (see Page 29).
Connection to outside (see Page 29) is required for all
mobile home installations and where building codes
require.
In all the other cases it is not mandatory to connect
the air intake directly to the stove (so that it draws
air directly from outside), but it is essential to ensure
an airflow to the stove for proper operation.
2.5.
CONNECTION TO THE FLUE PIPE
The stove must be connected to a UL listed pellet vent.
Pellet venting pipe (also known as L or PL vent) is constructed of two
layers with air space between the layers. This air space acts as an
insulator and reduces the outside surface temperature to allow a
clearance to combustibles of only 3 inches. The sections of pipe lock
together to form an air tight seal in most cases; however, in some
cases a perfect seal is not achieved. For this reason and the fact that
the Ego/Star operates with a positive vent pressure, we specify that the
joints also be sealed with high-temp silicone.
78.7” - 117” MAX
Follow vent manufacturers instructions regarding clearances to
combustibles. At the bottom of the flue pipe, provide an inspection cap
to allow periodic inspection and cleaning, which must be done
annually.
H >156”
Connect the stove to listed 3” or 4” pellet vent. Be sure to use a starting
collar to attach the venting system to the stove. The starting collar
must be sealed to the stove with high temp silicone caulking.
3-5 %
The stove must be connected to a flue pipe or an
internal vent system conforming to UL standards
Be sure to use approved pellet vent pipe wall and
ceiling pass-through fittings to go through
combustible walls and ceilings.
H >58.5”
IMPORTANT!
Follow manufacturers instructions regarding proper
installation of the flue system.
The Exhaust from the combustion of pellets may
cause discoloration on exterior walls. To eliminate
this possibility terminate the vent above the roof line.
Exhaust gasses are very hot and almost invisible.
They can cause burns on contact.

PELLET STOVES
Chapter 2
INSTALLATION AND USE MANUAL
page
12
A combustion blower is used to extract the combustion gases from the
firebox. This causes a negative pressure in the firebox and a positive
pressure in the venting system. The longer the vent pipe and more
elbows used in the system, the greater the flow resistance. Because of
these facts we recommend using as few elbows as possible and 20 feet
or less of vent pipe. The maximum horizontal run should not exceed 3
feet and must have a slope of not less than 3%. The vertical distance
between one 90‟ elbow or T connector and another must not be less
than 4 ½‟. If more than 20 feet of pipe is needed, the diameter should
be increased from 3" to 4" because a larger pipe causes less flow
resistance.
Using a draft gauge check that there is a minimum draft of 10 Pa when the
stove is burning at max level.
IMPORTANT! All sections of the venting must be
inspectable and removable to enable periodic
cleaning. All 90 degree elbows should be T
connectors to allow cleaning and inspection, which
must be done annually.
FOR CONNECTION TO THE FLUE PIPE, NOT MORE
THAN 3’ OF HORIZONTAL AND NOT MORE THAN
THREE 90° ELBOWS ARE ALLOWED
IT IS ALSO ADVISABLE TO USE 4” PELLET VENT FOR
RUNS OVER 20’ IN HEIGHT.
This type of connection ensures the ventilation of the
exhaust fumes in the event of a temporary power
outage.
Position the stove bearing in mind all the instructions and considerations
above.
See Page 18 for further details of vent configurations.

2.6. OPERATING PROBLEMS CAUSED BY DRAUGHT
DEFECTS IN THE FLUE
Of all the weather and geographical conditions which affect the
operation of a flue pipe (rain, fog, snow, altitude a.s.l., exposure to
sunlight, direction of facing), the wind is unquestionably the most
decisive. In fact, along with thermal depression caused by the
difference in temperature inside and outside of the chimney, there is
another type of depression or over-pressure: dynamic pressure caused
by the wind. An updraft always increases depression and hence
draught. A crosswind increases depression provided the cowl has been
installed properly. A downdraft always decreases depression, at times
inverting it.
Least favourable points
E.g. Downdraft at 45° of
8m/sec. Overpressure of 17
Pa
E.g. Crosswind 2: 8 m/sec
Depression of 30Pa
Downdraft
Most favourable position
WIND
High-pressure zone
Low-pressure zone
Besides the direction and force of the wind, the position of the flue and
the cowl with respect to the roof of the building and the surrounding
landscape is important.
The wind also influences the operation of the chimney indirectly by
creating high-pressure and low-pressure zones, not only outside the
building but inside as well. In rooms directly exposed to the wind (2),
an indoor high-pressure area can be created which can augment the
draught in stoves and fireplaces, but it can be counteracted by the
external high pressure if the cowl is situated on the side exposed to the
wind (1). On the other hand, in the rooms on the opposite side from
the direction of the wind (3), a dynamic depression can be created
which competes with the natural thermal depression developed by the
chimney, but this can be compensated for (sometimes) by locating the
flue on the opposite side from the direction of the wind (4).
IMPORTANT! The operation of the pellet stove is
noticeably sensitive to the conformation and position
of the flue which is adopted.

INSTALLATION
When installing and operating your MCZ Ego/Star Pellet Stove, respect
basic safety standards. Read these instructions carefully before you
attempt to install or operate the Ego/Star. Failure to do so may result in
damage to property or personal injury and may void the product
warranty. Consult with your local building code agency and insurance
representative before you begin your installation to ensure compliance
with local codes, including the need for permits and follow-up
inspections. Several issues must be addressed when selecting a suitable
location for your Ego/Star Pellet Stove. Observing required clearances to
combustible materials, the proximity to a safe chimney or venting
system, and the accessibility of electrical supply must all be considered.
In addition, selecting a location that takes advantage of the building's
natural air flow is also desirable to maximize the heating effectiveness
of the heater. In many cases, this is a central location within the
building. Adequate combustion and ventilation air must be provided.
See Page 11 about venting.
Place the stove on a noncombustible floor surface. If the floor surface is
made of a combustible material, (such as carpet, vinyl or wood), a floor
protector must be installed between the bottom of the unit and the
floor. The floor protector must be 3/8 inch minimum thickness of noncombustible material extending beneath the heater and extending to
the front, side, and rear as indicated in the figure below. Place the
stove away from combustible walls at least as far as shown in the
pictures on the right side for different installation conditions. Note that
the clearances shown are minimum for safety but do not leave much
room for access when cleaning or service is needed.

MOBILE HOME INSTALLATION
When installing the Ego/Star in a mobile home several requirements
must be followed:
1. The unit must be bolted to the floor. This can be done with 1/4" lag
screws through the 2 holes in the base plate shown in figure
2. The unit must also be connected to outside air (See page 29).
3. Floor protection and clearances must be followed as shown on page
16.
4. Unit must be grounded to the metal frame of the mobile home.
CAUTION: In mobile home installations the appliance must be
vented to the outside. The user must routinely inspect the point
where air is drawn in to insure that it is clear of leaves/debris
and ice or snow.
Floor fixing of the appliance
Due to high temperatures, the Ego/Star should be placed out of traffic
and away from furniture and draperies. Children and adults should be
alerted to the hazards of high surface temperatures and should stay
away to avoid burn to skin and/or clothing. Young children should be
carefully supervised when they are in the same room as the stove.
Clothing and other flammable materials should not be placed on or near
the Ego/Star Pellet Stove.

VENTING
3.4.1. Avoiding Smoke and Odors
Negative Pressure, Shut-down, and Power Failure:
To reduce the probability of back-drafting or burn-back in the
pellet burning appliance during power failure or shut-down
conditions, the stove must be able to draft naturally without
exhaust blower operation. Negative pressure in the house will resist this
natural draft if not accounted for in the pellet appliance installation.
Heat rises in the house and leaks out at upper levels. This air must be
replaced with cold air from outdoors, which flows into lower levels of
the house. Vents and chimneys into basements and lower levels of the
house can become the conduit for air supply, and reverse under these
conditions.
3.4.2. Vent Configurations
To reduce probability of reverse drafting during shut-down conditions,
MCZ strongly recommends:
• Installing the pellet vent with a minimum vertical run of five feet,
preferably terminating above the roof line.
• Installing the outside air intake at least four feet below the vent
termination.
To prevent soot damage to exterior walls of the house and to prevent
re-entry of soot or ash into the house:
• Maintain specified clearances to windows, doors, and air inlets,
including air conditioners.
• Vents should not be placed below ventilated soffits. Run the vent
above the roof.
• Avoid venting into alcove locations.
• Vents should not terminate under overhangs, decks or onto covered
porches.
• Maintain minimum clearance of 12 inches from the vent termination to
the exterior wall. If you see deposits developing on the wall, you may
need to extend this distance to accommodate your installation
conditions.
MCZ assumes no responsibility for, nor does the warranty
extend to, smoke damage caused by reverse drafting of pellet
appliances under shut-down or power failure conditions.

Wall outlet (method #1)
This method provides excellent venting for normal operation and
allows the stove to be installed closest to the wall. Two and a half
inches from the wall is safe; however, three inches allows better
access to remove the rear panel. The vertical portion of the vent
should be three to five feet high. This vertical section will provide
natural draft in the event of a power failure. Note: do not place
joints within wall pass-throughs.
3.4.2.2.
Wall outlet (method #2)
This method also provides excellent venting for normal operation
but requires the stove to be in-stalled farther from the wall. The
vertical portion of the vent should be three to five feet high and
at least three inches from a combustible wall. This vertical section
will provide natural draft in the event of a power failure. Note: do
not place joints within wall pass-throughs.

installed to the top of the flue, as shown in method method #6. This
method will provide natural draft in the event of a power failure. If the
chimney condition is questionable or if the flue size is larger than 8 X 8
inches, you should refer to method #6. If choosing this method,
increase the vent pipe to 4 in. at the stove.
3.4.2.4.
Installing into an existing fireplace chimney (method #4)
This method provides excellent venting for normal operation. Check
your local code requirements. Some areas require that a liner be
installed to the top of the flue, as shown in method #5. This method
also provides natural draft in the event of a power failure. The damper
area must be sealed with a steel plate or fiberglass. A cap should be
installed on the chimney to keep out rain. If the chimney condition is
questionable or if the flue size is larger than 8 X 8 inches, you should
refer to Method #5. If choos-ing this method, increase the vent pipe to
4 in. at the stove.

INSTALLATION OF AIR FILTER
Before placing the stove near the wall for connection to the flue
pipe and to the electrical mains, install the air filter provided
with the stove.
The cylindrical filter is composed of a metallic net and is already
installed on the stove
The filter must be inserted on the air inlet pipe 2”.
To remove it, slightly loosen the screw with the knob on the air inlet,
insert the filter matching it with the filter groove with the screw of the
knob and then secure it by tightening the knob.
Installation/removal of air filter
ATTENTION!
Never operate the stove without the air filter. MCZ
shall not be held liable for damage to internal
components if this instruction is not followed.
3.7.1. Outside Air
Connection to outside air is required for all mobile home installations,
and where building codes require. To install outside air use 2" I.D. flex
pipe. The maximum length run of this pipe is 15 feet. If a longer run is
needed, the size must be increased to 3". The air filter shall be moved
from the air inlet of the stove to the final part of the flex pipe, to keep
dust, birds, rodents, etc. out of the pipe.
3.8.
MAKING THE ELECTRICAL CONNECTIONS
Connect the supply cable first at the rear of the stove and then to an
electrical outlet on the wall.
The main switch located on the rear of the stove should be switched on
only when you want to light the stove.
If you do not intend to use the stove, it is advisable to
keep it switched off.

4. OPERATION
4.1.
PRE-LIGHTING WARNINGS
Do not touch the stove during the first lighting, as it
is during this phase that the paint sets. If you touch
the paint, you may expose the steel surface.
If necessary, touch up the paint with the aerosol spray in the original
colour (see the section "Accessories for pellet stoves").
It is good practice to provide plenty of ventilation in
the room during the initial lighting, as the stove will
give off a small amount of smoke and smell of paint.
Do not stay near the stove, and as previously mentioned, ventilate the
room. The smoke and the smell of paint will vanish after about one
hour of operation. There are no health risks involved.
The stove will be subject to expansion and contraction during the
stages of lighting and cooling down, and may therefore make slight
creaking noises.
This phenomenon is absolutely normal, the structure being made of
sheet steel, and must not be considered a fault.
It is extremely important to be sure not to take the stove to full heat
straight away, but to bring it gradually up to temperature.
If in manual mode, use low heating powers (for example 1 a-2a-3a).
During subsequent use, you will be able to run the stove on the highest
heat settings (e.g. 4a-5a), but remember not to keep the stove running
on full power for more than 60-90 minutes.
In this way you will avoid damage to the ceramic panels, the welds and
the steel structure.
At first lighting the stove is already in manual mode.
At first, it is advisable to use the only low and medium
heating levels (from first to third power level).
Do
not

PRE-LIGHTING CHECK
Check that all the safety conditions described above have been met.
Make sure you have read and completely understood the contents of
this instruction booklet.
Remove any components which might burn from the firebox and from
the glass (various instructions and adhesive labels).
Check that the grate A is properly positioned and rests correctly on the
base.
A
After long periods of disuse, remove from the hopper (using
a vacuum cleaner with an extension) any remains of
pellets which have lain there for some time, since they may
have absorbed moisture, which changes their original
characteristics and makes them unsuitable for burning.
4.3.
LOADING THE PELLETS
Fuel is loaded from the upper part of the stove by opening a door. Pour
the pellets in the hopper. When empty, it will hold slightly more than a
15 kg sack.
This is easier if performed in two steps:
Pour half of the contents into the hopper and wait for the fuel
to settle on the bottom.
Then pour in the rest
Never remove the protection grille in the hopper.
When filling, do not let the sack of pellets touch any
hot surfaces.
Do not place any type of fuel in the hopper other than
pellets that are compliant with the specifications
provided previously.

4.4.1. Control panel logic
Reported below is some useful information to understand the
navigation logic and use the control panel:
The luminosity of the control panel is switched off after about
30” seconds of the keyboard being inactive. To switch on the
back lighting again just press any of the buttons on the panel.
The first screen that appears displays the operating status of
the stove (ON, OFF, LIGHTING, SHUTDOWN..) that alternates
with any other settings activated (TIMER, SLEEP, AUTO ECO..)
By pressing any of the 4 keys around the display (C D E F) you
access the stove's operation settings screen (level of the flame,
fan, set temperature, manual or automatic mode..). From this
level the 4 keys around the display assume “dedicated”
functions, i.e. they directly refer to the corresponding words
that appear in the 4 corners of the display (e.g.: the word in
the top right hand corner refers to the D key).
When a setting is modified in any menu level without
confirming the modification using the “OK” key and leaving the
keypad inactive for some seconds, the initial screen reappears
and the modifications are not saved.
If from any menu level the on/off (B) key is briefly pressed, the
display is automatically taken back to the initial screen (stove
operating status) without saving any modifications not
confirmed with the “OK” key.

4.4.3. General characteristics of the LCD remote control
The EGO and STAR stoves are mainly controlled by the control panel
that is found above the stove. As an accessory, it is in any case possible
to purchase the remote control that manages the main functions:
on/off, power adjustment, hot air fan speed adjustment, automatic
function.
Keep the remote control away from direct heat and
water.
It is advisable to keep it out of the reach of children.
4.4.4. Type of batteries and replacement
To substitute the battery, it is necessary to extract the battery-holder
(as shown on the figure on the back of the remote control), and remove
or insert the batteries following the symbols printed on the remote
control and the battery itself.
Operation requires 1 CR 2025 Lithium battery.
Used batteries contain metals which are harmful for the
environment; they must therefore be disposed of
separately in the special containers.
If the remote control is off due to the absence of
batteries, it is possible to control the stove from the
control panel, located in the upper part of the stove.
The batteries provided have a limited lifespan to allow
first lighting of the stove and for the user to learn how
to use the device.
When replacing the batteries, ensure correct polarity
by observing the symbols on the internal
compartment of the remote control.

4.6.2. Note: first ignition
The first attempt at ignition may not be successful,
since the auger is empty and it is not always able to
fill the grate with required amount of pellets in time
to insure normal ignition
CANCEL THE ALARM CONDITION FROM THE
CONTROL PANEL (see paragraph 4.14)., REMOVE
PELLETS IN THE GRATE AND REPEAT LIGHTING
After repeated attempts at lighting, if there is no flame even though
pellets are flowing normally, check that the grate is correctly positioned.
It must be placed where it sits perfectly to its housing and free
of any ash or carbon build up. If no abnormalities are found, it
means that there may be a problem with the stove components or that
installation may not have been carried out correctly.
REMOVE THE PELLETS FROM THE BURNER AND
CONTACT AN AUTHORISED MCZ TECHNICIAN.
4.7.
OPERATING MODE
STAR-EGO stoves have two operating modes: MANUAL and
AUTOMATIC.
4.7.1. Manual and automatic
The stove can operate in one of these two different operating modes.
MANUAL mode allows only adjustment of the flame from out-put
power 1 to power 5, ignoring any ambient temperature measurement.
This mode is indicated by the word MANU on the control panel.
AUTOMATIC mode lets you set the desired temperature in the room
where the stove is installed. The stove will control its power
automatically in order to reach and maintain the set temperature in the
room. This mode is indicated by the word AUTO on the control panel.

Room sensor
The room sensor (B) is placed behind the stove near the switch. You
are advised to extract the room sensor so that it extends out as in
figure (about 2 ½”). This way it is not thrown off by the heat of the
stove. It is advisable to do this during installation, since before
extracting the probe (B) it is necessary to take off the clamp (C) that
keeps it connected; operation possible by working inside the stove thus
without the sides. To extract the probe (B) it is necessary to unscrew
the protection cap (A) and slowly pull the probe (B). After extracting
the probe (B) sufficiently, close the protection cap (A) again.
ATTENTION! Once the clamp that binds the probe wire
is taken off, avoid it coming into contact with the hot
parts of the stove.

4.7.4. Automatic mode with AUTO-ECO
This mode changes stove operation in automatic mode. Upon
reaching the temperature set by the user, the stove goes to power level
1 for a short period of time. At that point if the temperature remains
constant and above the set temperature the stove will shut down. The
stove comes back on automatically only when the room requires heat
again, but not before a period of time has passed for the stove to cool
off. This option is advisable only if the stove works in highly insulated
rooms or where there is low heat dispersion over time.

Example of operation in AUTO-ECO mode
If the room temperature detected by the sensor and highlighted on the
control panel is 15°C and the set temperature is 20°C, the stove will
follow a pre-established ramp up to the 5th power. Once 20°C is
reached, it goes into standby mode (STANDBY). When the room
temperature drops below the value set on the control panel (for
example 18°C) and a sufficient shutdown time has elapsed, the stove
will come back on automatically and continue running until again
reaching 20°C. If the temperature read by the room sensor remains
above the value set on the thermostat (for example 20-21°C) the stove
will remain off.
In this mode, lighting can be carried out by the user by resetting the
thermostat temperature to a value greater than that in the room, or by
shutting down the stove by pressing button B for a few seconds and
then pressing the same button to re-light the stove.
The “AUTO-ECO” mode does not need to be reset as it remains in
memory from the last use.

display the word Ma P00 will appear (where the word P00 flashes),
proceed with the programming mode until the day SU=Sunday.
If for a given day of the week you do not want to set any
program, select program 00 and continue with programming.
If a timer program is active but the user decides to
start/stop the stove in advance, the command given
by the user overrides the timer and is carried out. The
next command from the timer is obviously
disregarded.
Example: if the timer calls for the stove to be started
up at 10:00 but the user decides to start it
at 9:00, by pressing button 5 the stove will
come on. At 10:00, the timer, which was to
order start-up, will be disregarded.
IMPORTANT NOTE
It takes 10 to 15 minutes for the stove to start up.
Take this into account when setting the start time. Likewise,
stove shutdown requires about 30 minutes, during which
the heat stored up by the stove is still released into the
room.
Keep this in mind for substantial fuel savings.

4.11. PRE-SET WEEKLY AND DAILY PROGRAMS
4.11.1.
Weekly programs
The weekly programs selected by MCZ and stored in the memory of the
control panel were designed to meet the needs of most users who are
out of the home during working hours (factory workers, shopkeepers,
office workers, shift workers) as well as those who are usually at home
(homemakers, senior citizens, etc.).
Also, programming has been provided for those who use the stove in a
weekend home (e.g. a home in the mountains) and want to find the
home warm when they get there.
If you have even more specific needs which are not met by any of these
weekly programs, you can customize weekly program P99 using seven
different programs for each day of the week (see chapter 4.11.2).

4.13. SAFETY DEVICES
The stove is fitted with the following safety devices:
SMOKE TEMPERATURE SENSOR.
Monitors the temperature of the smoke, and gives permission for
start-up or shuts the stove down when the smoke temperature
falls below the preset value.
PELLET HOPPER TEMPERATURE SENSOR.
If the temperature exceeds the preset safety level, it immediately
shuts down the stove, and has to be reset, after the stove has
cooled. This must be done before the stove will restart.
ELECTRICAL SAFETY
The stove is protected against violent surges of current by the
main fuse, which is located on the control panel at the rear of the
stove. Other fuses to protect the electronic boards are to be found
on the boards themselves.
FAILURE OF THE COMBUSTION BLOWER
If the blower stops, the board shuts off the supply of pellets, and
an alarm code is displayed.

PROHIBITED
THE
SAFETY
DEVICES
IS
It is only after eliminating the cause which gave rise to the
intervention of the safety system, that it is possible to relight
the stove and thus reset the automatic operation of the
sensor. To understand which anomaly has occurred, consult
this manual at paragraph 4.14 which explains what to do
based on the alarm message the stove displays.
ATTENTION
If the stove is not used as described in this instruction booklet,
the manufacturer refuses to accept any responsibility for
damage to persons and property that may arise. The
manufacturer furthermore refuses to accept responsibility for
damage to persons and property arising from the failure to
observe all the rules contained in the manual and in particular:
Failure when carrying out works of maintenance, cleaning
and repair to adopt all necessary measures and
precautions
Tampering with the safety devices.
Removing the safety devices.
Failure to connect the stove to an efficient system for the
discharge of smoke.
Failure to check in advance that the room where the stove
is to be installed is adequately ventilated.
4.14. ALARM SIGNALS
Should an operation problem occur, the stove enters a shutdown phase
and an alarm informs the user of the type of fault that occurred using a

4.15. Exiting alarm condition
If an error code or alarm interrupts the operation of the stove you can
re-set the normal operation of the stove by pressing the on/off key for
a long time. After a short verification phase if the cause that caused the
alarm does not persist, the stove leaves the alarm status and it may
restart.
4.15.1.
Shutdown of the stove
The following things can cause stove shutdown:
Overheating of the stove body (“A03”)
Overheating of the exhaust (“A04”)
During the function of the stove, an uncontrolled air intake
occurred in the combustion chamber or an obstruction in the flue
pipe. (“A05”)
WHAT TO DO:
When the stove is cold: if the message “A03” appears: The structure is
too hot because the product has been operating for too long at
maximum power, or it is poorly ventilated, or the air fans are faulty
When the stove is sufficiently cold, press button B of the control panel
or OFF on the remote control to cancel the alarm A03. Once the alarm
is cancelled it is possible to relight the stove normally.
If the alarm “A04” appears the stove shutdown in automatic, leave it
to cool down for a few minutes and then re-light. Cancel the alarm and
re-light.
If the alarm “A05” appears: it is caused by prolonged opening of the
fire door or by substantial air infiltration (e.g. combustion blower
inspection plug missing). If not caused by these factors control the
smoke outlet protection against the strong wind and if necessary clean
the smoke duct and the flue pipe.
Only after the cause of the blockage has been permanently
eliminated can a fresh attempt to relight the stove be made.

5. MAINTENANCE AND CLEANING
ATTENTION!
All cleaning of all parts must be carried out with the
stove completely cold and unplugged.
The stove does not need much maintenance if used with
certified quality pellets.
5.1.
DAILY AND WEEKLY CLEANING BY THE USER
Example of clean grate
5.1.1. Before each lighting
Using a suitable tool clean the grate “F” of ash and any incrustation
which could obstruct the passage of air.
In the case of pellet depletion, unburnt pellet in the grate could
accumulate in the hopper. Always empty the residuals from the grate
prior to each lighting.
Example of dirty grate
REMEMBER THAT ONLY A CORRECTLY POSITIONED
AND CLEAN GRATE CAN GUARANTEE THE OPTIMAL
LIGHTING AND OPERATION OF YOUR PELLET STOVE.
For good cleaning of the grate, pull it completely out of its housing and
thoroughly clean the grate and holes on the bottom. If you use goodquality pellets, you will normally only need to use a paintbrush to
restore the perfect condition of the component. For tough incrustations,
use the steel tool provided with the stove.
G
5.1.2. Check every 2/3 days
F
Clean and empty the ash drawer, watching out for hot ash.
Disposal of Ashes: Ashes should be placed in a metal container with a
tight fitting lid. The closed container of ashes should be placed on a
non-combustible floor or on the ground, well away from combustible
materials, pending final disposal. If the ashes are disposed of by burial
in soil or otherwise locally dispersed, they should be retained in the
closed container until all cinders have been thoroughly cooled. No other
waste shall be placed in this container.
Only if the ash is completely cold, it is possible to use a vacuum
cleaner to remove it. Use a drum-type vacuum cleaner that is suitable
for picking up particles of a certain size.
Cleaning the ash collection compartment
Experience, and the quality of the pellets used, will determine the
frequency of cleaning.
It is however advisable not to let it exceed 2 or 3 days.
Once the operation is finished, reinsert the ash drawer below the grate
making sure it is properly seated.

5.1.3. Cleaning the glass
For cleaning the ceramic glass, the use of a dry brush is recommended,
or if it is very dirty, use stove glass cleaner and a soft cloth.
ATTENTION!
Do not clean the ceramic glass until its surface has
been thoroughly cooled.
Do not use abrasive products and do not spray the
cleaning product on the glass of the painted parts or
on the gaskets of the fire door (ceramic fiber cord)
Cleaning the glass
In case of door glass break, it must be replaced with a product of the
same type. Order it referring to code #4 described in chapter 8.2.1. The
glass used in all MCZ stoves is a 5mm ceramic glass type resistant to
1400°F.
To replace the glass remove the door and lay it down in a horizontal
plane. Then unscrew the parts 5a and 5b (refer to figure in chapter
8.2.1). Replace the broken ceramic glass with a new identical one and fix
it again to the door structure, being careful to keep the glass gasket in
the same position as it was before removing the glass.
ATTENTION!
Use only original MCZ ceramic glass for substitution.
The manufacturer refuses to accept any responsibility
and the guarantee lapses if this condition is not
respected.
5.1.4. Cleaning of the air filter
At the back of the stove, at the combustion air intake tube Ø 5 cm,
there is a metallic mesh air filter. Its purpose is to keep dirt out of the
motor body and the internal sensor.
It is advisable to check every 15/20 days whether the filter is clean.
Remove lint or any other material which may have been trapped by the
filter.
Checking and cleaning will be required more frequently if there are pets
in the home.
For cleaning, just turn the knob that holds the filter on the air intake
pipe and remove the filter by turning in the direction indicated by the
arrow. Clean it with a brush, damp cloth or compressed air.
The filter is made of metallic mesh. It is soft and
malleable to the touch. Therefore, when cleaning it,
be careful not to crush it or damage it in any other
way. If it is broken it must be replaced
Removing the air filter for cleaning
ATTENTION!
Never operate the stove without the air filter. MCZ
shall not be held liable for damage to internal
components if this instruction is not followed.

5.2.1. Cleaning of the heat exchanger
After the winter you will need to clean the compartment where
discharge smoke passes.
This cleaning must be done in order to remove all combustion residues
before time and humidity let them harden and make them difficult to
remove.
CLEANING OF HEAT EXCHANGER:
CLEANING THE UPPER COMPARTMENT
With the stove cold remove the cast iron top “A”, remove the sides as
indicated in. Par. 3.3, take off the cast iron front top “C”. At this point
remove the plug (by unscrewing the screws) “E”, remove the
exchanger D and access the inspection hole for cleaning (see arrow):
Using a stiff rod or a bottle brush, scrape the inner walls of the fire box
so that the ashes drop into the part below “H”.
Cleaning the upper compartment
Clean and refit all the components by using a new front gasket.
CLEANING THE LOWER COMPARTMENT
Remove the ash drawer “G” , unscrew the screws and remove the plug
“E” and with the nozzle of a vacuum cleaner to remove the soot and
ash which has accumulated in the exchanger “H”. Also remove the
grate “F” and clean it every 2/3 days as explained in chap. 5.1
It is worthwhile to carry out the cleaning of the upper exchanger at the
end of the season and possibly by an authorised MCZ technician in
order to replace the gaskets that are below plug “C” and “E”
CLEANING OF VENT SYSTEM AND GENERAL CHECKS:
Clean the vent system, especially in the area of the T connectors,
elbows and any horizontal stretches of pipe.
For information on cleaning the flue pipe, contact a professional
chimney sweep.
Check the seal of the ceramic fibber gaskets on the door of the stove. If
necessary, order new gaskets from the retailer for replacement or
contact an authorized service centre.
F

G
Cleaning the lower compartment
ATTENTION:
The frequency with which the smoke discharge
system is cleaned should be determined based on the
type of use that is made of the stove and the type of
installation.
MCZ suggests relying on an authorized service centre
for end-of-season cleaning and maintenance and a
general check of the stove's components.

5.2.2. Shutting the stove down (end of season)
At the end of season, before shutting down the stove, we recommend
completely removing pellets from the hopper with the use of a vacuum
cleaner with an extension.
If the stove is to be disconnected and stored, the stove must be
unplugged and placed in a dry place protected from the
elements. For greater safety, especially if there are children
around, we recommend removing the power cord from the rear
of the stove.
Upon re-start, when pressing the main switch (located on the back of
the stove) does not make the control panel display light up, it could
mean that the service fuse needs replacing.
On the rear of the stove there is a fuse compartment which is located
underneath the supply socket. Use a screwdriver to open the fusecompartment and if necessary replace them (3.15 AT delayed)
5.2.3. Check of internal components
ATTENTION!
The check of the internal electro-mechanical
components must be carried out only by qualified
personnel with technical knowledge of electricity and
combustion.
We recommend that an annual maintenance service is carried out,
preferably by the dealer or service technician. The essential part of this
service is a visual and functional check on the internal components:
The following is a summary of the checks and/or maintenance tasks
which are indispensable for the correct operation of the stove.
